摘要： A method and plant for the thermal treatment of friction elements including a convective heating step which is performed within a convective tunnel oven. The friction elements are arranged laid, in an orderly manner, upon a plurality of trays each tray having a perforated resting plate upon which the friction elements are laid in a position next to one another only, but not overlapped. The trays are piled on top of each other whilst being kept distanced from one another in a stacking direction by an amount that is greater than the thickness of the friction elements. Groups of piled up trays containing the friction elements are arranged side by side on belt conveyor means that pass through the tunnel oven in order to transport the friction elements therethrough.

摘要： A tunnel oven and associated method for the heat treatment of friction elements, and in particular of braking elements such as brake pads is provided. The friction elements are arranged on a resting surface of a conveyor device, are moved between an inlet opening and an outlet opening of the tunnel oven, and are heated by irradiation by at least one heating device. The heating device includes a radiating plate made from stainless steel arranged facing the conveyor device and heated by electromagnetic induction by means of at least one inductor arranged facing the radiating plate and spaced apart therefrom on the side opposite to the conveyor device. A cooling air flow for the braking elements between the resting surface and the radiating plate is directed in counterflow to a feeding direction of the conveyor device.
